CABLE-GUIDE FOR SHEAVES AND PULLEYS.

. To all whom it may concern.-

Be it known that 1, WILLIAM D. Jones, residing at Patillas, Porto Rico,have invented certain new and useful. Improvements in CableGuides forSheaves and Pulleys, of which the following is a specification.

My invention relates to cable guides for sheaves and pulleys, andparticularly to a cable guide adapted to be used in connection with thattype of dumping car wherein the car dumping mechanism is operated by anair actuated piston controlled by a cable.

In this form of dumping car a cable guide is mounted adjacent to andextends partially around the circumference of the sheave or pulley, andthis guide is mounted upon the bolster column. This guide so mounted, isvery liable to break or to be bent due principally to the cars runningoff the track, which occurs very often. When so broken or bent the cableruns off the sheave or pulley losing control of the piston and thiseither causes the piston head to burst or smashes the cylinder head,thus rendering the dumping mechanism inoperative. To remedy this, it isnecessary to remove the old bolster column and put in an entirely newbolster col.- umn, even though the column itself is as good as new, thecolumn being useless, however, because of the breaking of the guide.This entails not only an expense, due to the actual cost of the columnitself, but also loss of time during which the car is laid up forrepairs and the expense of the wages to the repairers.

The main object of my invention is, therefore, to so construct a cableguide for this type of cars that it may be readily removed or replacedin case of breaking Without removing or replacing the bolster column andwithout consequent loss.

A further object is to so construct the guide that not only is iteffective as a cable guide per 86 but that it also shall form a washerto take the place of the ordinary washer disposed between the sheave andthe cotter pin holding the sheave in place.

A further object is to provide a guide adapted tobe placed either on theright or "left hand side of a pulley so that one guide may be used fordifierent situations.

A further object is to so construct the Specification of Letters Patent.

guide that the cotter pin shall positively hold the guide in a setposition.

My invention is illustrated in the accompanying drawings, wherein Figurel is a fragmentary perspective view of a portion of a dumping car andcable sheave showing my invention applied to the sheave. Fig. 2 is ahorizontal section taken diametrically across the sheave and showing myattachment applied to the sheave hub. Fig. 3 is a face view of thesheave, a portion of the bolster column and my cable guide. Fig. 4 is aface view of the cable guide detached from the sheave. Fig. 5 is afragmentary section on the line 55 of Fig. l, showing one of the studs,which are disposed on each side of the cotter pin groove.

Referring to these drawings, it will be seen that I have shown my guideas applied to a cable sheave mounted in connection witha dumping car ofthe type described, only so much of the car being shown as willillustrate the application of my invention.

Referring to Fig. 1, A designates the bolster column, and B a bracketattached to the bolster column and projecting out therefrom and carryingan arcuate guide C. Projecting from the bolster column is a fixed hub 2upon which the sheave D is rotatably mounted. This sheave may have anyordinary or desired form. The arcuate cable guide C extends transverselyacross the face of the pulley but is spaced therefrom and extendslongitudinally along a portion of the circinnference of the pulley. Allof these parts are old and form no part of my invention. The extremityof the hub 2 is transversely pierced for the passage of a cotter pin 3of the usual form.

My improved guide comprises an annular terminal portion designated 4:which has an opening?) in its center adapted to fit over the projectingend of the hub 2 and an arm 6 which extends out from the terminalportion, this arm being angularly bent, as at 7, so as to extend acrossthe edge face of the sheave. The extremity of this angular portion 7being again bent inward, that is, toward the axis of the sheave, as at8, and ex tending over the margin of the sheave.

The cable guide may be mace, of course, of any suitable material andhave any desired and nearly five inches in length.

In order that the guide may be held in proper angular relation to theaxis of the pulley, I provide means upon the outside T face of theannular portion at of the guide which will engage the cotter pin 3 andhold the guide in its proper position. To this end I preferably form theouter face of the annular portion of the guide with a recess or groove 9which extends diametrically across the annular portion ofthe guide andwhich is adapted to receive the two legs of the cotter pin.

In order to permit the guide to be used on one or the other side of apulley and further adapt the guide to be used with pulleys in anydesired situation I preferably provide two of the cotter pin engaginggrooves 9. The second of these grooves 15 designated 9 and differs inits angular posit-ion from the groove 9.

In order to prevent any movement of the guide from its proper angularrelation to the cotter pin I preferably provide studs 10 which aredisposed on each side of the grooves 9 and 9 These studs, preferably,are somewhat conical in form and may either be cast integral with theguide in case the latter is cast, or may be separate from the materialof the guide and attached thereto in any suitable manner, as by formingeach stud with a reduced shank extending through and mounted upon theinner face of the guide. These studs are so disposed j that they willengage with the cotter pin 1 in case a strain comes upon the guide, andwill prevent any rotation of the guide upon the hub.

It will be noted that in the guide, as de scribed, the annular portion 4forms a washer disposed between the inner face of the cotter pin and theadjacent or outer face of the sheave.

I have found in practice that these cable guides are exceedinglyeffective for the puri pose described and that they positively hold thecable E in place and prevent it running oif the sheave.

Having described my invention what is claimed as new is.

1. A cable guide for sheaves comprising an annular portion adapted tofit over the hub of the sheave, and an arm projecting from the annularportion and extending at right angles at its outer end, the annularportion of the guide being formed With-a l pair of diametricallyextending cotter pin grooves, the grooves being set at an angle to eachother to permit the annular portion to be disposed on the right hand orleft hand j side of a sheave. ecting arm 6 thereof about two inches wideA cable guide for sheaves having an annular portion adapted to fit overthe hub of the sheave and formed with an outwardly projecting memberadapted to extend over said sheave and having two diametrically disposedcotter pin grooves, the grooves crossing each other whereby the guidemay be reversed in position with relation to the sheave.

8. The combination with a hub, a sheave mounted thereon, and means forholding the sheave in place upon the hub, of a cable guide comprising aplate formed with an annular portion at one end adapted to engage overthe hub and against the sheave, said plate extending outwardly beyondthe sheave and being then bent across the periphery of the sheave, andmeans for holding the guide in a fixed angular position with relation tothe hub.

r. The combination with a hub, a sheave mounted upon the hub, and acotter pin passing through the hub, of a cable guide comprising a platehaving an annular portion at one end adapted to fit over the hub,

said annular portion having a diametrically disposed groove upon itsouter face adapted to partially embrace the cotter pin, said plateextending outward to the circumference of the sheave and being thenangularly bent across the face of the sheave.

5. The combination with a hub, a sheave mounted thereon, and a cotterpin extending therethrough of a cable guide comprising a plate having anopening at one end adapted to fit over the hub and having a plurality ofgrooves in its face,said grooves extending diametrically across theopening, and being adapted to partially embrace the cotter pin, theouter extremity of the plate being angularly bent.

6. The combination with a hub, a sheave mounted upon the hub, and acotter pin, of a cable guide comprising a plate having an opening at itsend adapted to fit over the hub, this end of the plate being formed witha plurality of grooves extending diametrically across the opening andadapted each to partially embrace the cotter pin, the face of the platebeing provided with spaced lugs disposed one on each side of eachgroove, and said plate at its extremity being angularly bent over theface of the sheave.

In testimony whereof I afix my signature in presence of two witnesses.
